On the conference call with investors, Zuckerberg tried to portray each of these recent, high-valuation deals as extremely rare and not something that Facebook is going to embark on again in the next few months.

“I guess you should not expect us to make a couple of multi-billion-dollar acquisitions over the next couple of months,” Zuckerberg said. “There are not many candidates to be the next computing platform.”

Zuckerberg said that Oculus could turn out to be the next big computing and social platform, bringing friends and families together in a virtual world that is amazingly real and free of the jerkiness and headache-inducing quality that dogged virtual-reality systems of the past.

He said that the development kit created by Oculus has already led to some amazing uses of the company’s virtual-reality goggles, such has a teleporting app to visit far-away places.

“It’s like being there,” Zuckerberg said, as he explained to Wall Street how Oculus was using low-cost commodity components for super-fast graphics rendering, resulting in the ability to render “a full world, without motion sickness.”

When asked by one analyst about the fruits from any of these big deals so far, Facebook CFO David Ebersman said that Instagram, which Facebook bought for $1 billion two years ago, had already surpassed the company’s target for user growth, but he did not give any financial information as to how the photo-sharing app was boosting the bottom line.

Still, investors are now wondering if, when and how these hefty deals are going to pay off.
